Description

Technical Field

[0001] This utility model belongs to the field of automotive pedal testing technology, specifically relating to an automotive pedal testing device. Background Technology

[0002] In the field of modern automotive engineering, the pedals are key components for controlling the vehicle's driving status. Their reliability and accuracy directly affect the safety of drivers and passengers and their driving experience. Therefore, pedal testing has become an indispensable part of automobile manufacturing, quality inspection, and after-sales maintenance.

[0003] Chinese Patent CN221055938U discloses a vehicle brake pedal force detection device, relating to the field of brake pedal force detection. The device includes a main body with a handbrake interface on one side of its top and a brake pedal interface on the other side. A signal transmission line is located on the top of the brake pedal interface, and a pressure sensor is located on one side of the signal transmission line. A rubber block is located at the bottom of the pressure sensor, and a set of Velcro straps is located at each of the four corners of the top of the pressure sensor. The pressure sensor is divided into two parts: a cylindrical top and a square bottom. The rubber block is smaller than the bottom of the pressure sensor. The rubber block and four sets of Velcro straps increase friction with the brake pedal, and the four sets of Velcro straps wrap around the bottom of the brake pedal and attach to fix the position of the pressure sensor, preventing the pressure sensor from changing position or even slipping off the brake pedal surface when the user applies pressure, thus affecting the brake pedal force test results.

[0004] During prolonged use, the adhesive strength of the Velcro may gradually weaken, and the friction of the rubber block may decrease due to wear and tear. This could result in poor fixation, displacement of the pressure sensor, affecting detection accuracy, and making it difficult to protect the main body of the detector. External factors may damage the main body of the detector, thus reducing the service life of the equipment. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 4 As shown, this utility model provides an automobile pedal detection device, including a detector 1. A signal transmission line 6 is provided on the right side of the top of the detector 1, and a pressure sensor 7 is provided on one side of the signal transmission line 6. The detector 1 includes a first limiting mechanism 5 for protection and a second limiting mechanism 8 for fixing.

[0024] The pressure sensor 7 has a second sliding groove 71 symmetrically opened on the right side inside, and a connecting plate 81 symmetrically installed on the left side. The connecting plate 81 has a third sliding groove 82 inside, and an L-shaped clamping plate 84 is slidably connected to the inner wall of the third sliding groove 82. A second spring 83 is movably connected to the top of the L-shaped clamping plate 84. The top of the second spring 83 is fixedly connected to the inner wall of the third sliding groove 82. A pull plate 85 is provided on the right side of the pressure sensor 7. Both ends of the pull plate 85 are fixedly connected to the connecting plate 81. A sliding rod 86 is fixedly connected to the left side of the connecting plate 81. The sliding rod 86 is slidably connected to the inner wall of the second sliding groove 71. A third spring 87 is movably connected to the left end of the sliding rod 86. One end of the third spring 87 is fixedly connected to the inner wall of the second sliding groove 71.

[0025] In this embodiment, when the brake pedal needs to be detected, the pull plate 85 is pulled first. The pull plate 85 drives the connecting plate 81 and the slide rod 86 on the right side of the pressure sensor 7 to move outward, and stretches the third spring 87, realizing the horizontal expansion of the overall structure. When the connecting plate 81 on the right side of the pressure sensor 7 moves to the appropriate position, the pressure sensor 7 is placed on top of the brake pedal. Then the pull plate 85 is released. Under the action of the rebound of the third spring 87, the connecting plate 81 on the right side of the pressure sensor 7 moves inward, thus fixing the pressure sensor 7 and the brake pedal in the horizontal direction.

[0026] Then pull down the L-shaped clamp 84. At this time, the L-shaped clamp 84 will slide down along the third slide groove 82, and the second spring 83 at its top will be stretched. When the L-shaped clamp 84 moves down to the appropriate position, release the tension on it. Under the rebound action of the second spring 83, the L-shaped clamp 84 will move back up, thereby fixing the pressure sensor 7 and the brake pedal in the vertical direction. This design is relatively simple to operate and can ensure the stability between the pressure sensor 7 and the brake pedal, thereby ensuring the stability and accuracy of the detection process.

[0027] In a further embodiment, T-shaped grooves 11 are symmetrically provided on both sides of the front end of the detector 1, and a protective shell 4 is provided at the front end of the detector 1. T-shaped blocks 41 are fixedly connected to both sides of the rear end of the protective shell 4, and the T-shaped blocks 41 are slidably connected to the inner wall of the T-shaped grooves 11.

[0028] In this embodiment, when the detector 1 is no longer in use, the protective shell 4 is pushed upward. The protective shell 4 slides upward in the T-groove 11 through the T-shaped block 41, so that the protective shell 4 can fit tightly against the front end of the detector 1. This can effectively prevent dust, moisture and other impurities from easily entering the detector 1 and causing damage, thus improving the service life of the equipment.

[0029] In a further embodiment, a slot 13 is provided at the top front end of the detector 1, and a limiting block 55 is fixedly connected at the center of the top of the protective shell 4, with the limiting block 55 fitting into the inner wall of the slot 13.

[0030] In this embodiment, when the protective shell 4 is installed, after the T-shaped block 41 slides along the T-shaped groove 11 to a certain extent, the limiting block 55 can be accurately embedded in the slot 13, providing a clear "positioning mark" for the installation of the protective shell 4, ensuring that the protective shell 4 is in the best and most accurate position every time it is installed.

[0031] In a further embodiment, a first sliding groove 12 is provided at the center of the top of the detector 1, a push block 51 is provided above the detector 1, a connecting rod 52 is fixedly connected to the bottom end of the push block 51, a latch 53 is fixedly connected to the bottom end of the connecting rod 52, the latch 53 is slidably connected to the inner wall of the first sliding groove 12, and the front end of the latch 53 is fitted into the inner groove of the limiting block 55.

[0032] In this embodiment, when the limiting block 55 slides into the slot 13, it will touch the latch 53, causing the latch 53 to move towards the first slide groove 12 and causing the first spring 54 to retract. When the limiting block 55 is fully embedded in the slot 13, under the action of the elastic force of the first spring 54, the latch 53 returns to its original position and is embedded in the internal slot of the limiting block 55, further ensuring the fitting accuracy between the protective shell 4 and the detector 1, ensuring that the protective shell 4 can protect the detector 1 in all directions and avoid protection loopholes due to positional deviation.

[0033] In a further embodiment, a first spring 54 is movably connected to the rear end of the latch 53, and the rear end of the first spring 54 is fixedly connected to the inner wall of the first groove 12.

[0034] In this embodiment, the first spring 54 can assist the latch 53 to accurately embed into the internal slot of the limiting block 55, making the fit between the latch 53 and the limiting block 55 tighter and enhancing the connection stability between the protective shell 4 and the detector 1.

[0035] In a further embodiment, a display screen 2 is fixedly installed on the top front end of the detector 1, and several buttons 3 are fixedly installed on the lower front end of the detector 1.

[0036] In this embodiment, the display screen 2 can directly display various key data during the vehicle pedal testing process, and the button 3 allows the testing personnel to conveniently perform various operations on the testing instrument 1.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
